Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In embodiment 1 of the umbrella stand type floor drain assembly of the present invention, as shown in fig. 1 to 3, the umbrella stand type floor drain assembly includes a drain pipe structure 1, a filter cover 2, and a tightening structure 3 detachably installed in the drain pipe structure 1, the tightening structure 3 includes a threaded rod 31, a nut 32, and an umbrella stand structure 33, the threaded rod 31 is rotatably installed on the filter cover 2, the upper end of the threaded rod 31 is provided with a screwing part 310, and the nut 32 is in threaded fit with the threaded rod 31; the umbrella stand structure 33 is connected between the filter cover 2 and the nut 32 in a rotation stopping way, the umbrella stand structure 33 is provided with a jacking arm 330 which is used for radially expanding outwards when the nut 32 is axially close to the filter cover 2, and the end part of the jacking arm 330 is in jacking fit with the inner wall of the drainage pipe structure 1; the inner wall of the drainage pipe structure 1 is further provided with a blocking structure in a protruding manner, and the blocking structure is in axial blocking fit with the radially outward-expanded jacking arm 330.

The umbrella stand type floor drain assembly is provided with a jacking structure 3, a threaded rod 31 is rotatably arranged on a filter cover 2, a screwing part 310 is arranged at the upper end of the threaded rod 31, and an umbrella stand structure 33 of the jacking structure 3 is connected between the filter cover 2 and a nut 32 in a rotation stopping manner; when the screwing part 310 is operated to rotate the threaded rod 31, the nut 32 is driven to move upwards through the thread matching effect of the nut 32 and the threaded rod 31, the umbrella frame structure 33 is axially extruded when the nut 32 moves close to the filter cover 2, the umbrella frame structure 33 generates radial expansion movement along with the axial extrusion, the radially outward expanded jacking arm 330 is tightly matched with the inner wall of the drain pipe structure 1, the umbrella frame structure 33 is tightly connected with the drain pipe structure 1, and the filter cover 2 is reliably arranged at the pipe orifice of the drain pipe structure 1.

In addition, a stopping structure is further protruded from the inner wall of the drainage pipe structure 1, and the radially outward expanding tightening arm 330 is axially stopped and matched by the stopping structure, so that the filter cover 2 is effectively prevented from being forcibly removed outwards. This umbrella stand formula floor drain subassembly need use to revolve to twist instrument just can dismantle filter cover 2, has avoided appearing the mistake and has torn the condition of losing open, and this floor drain subassembly's core part lies in umbrella stand structure 33 moreover, compares in the spare part of current floor drain still less, and overall structure is simpler.

The umbrella stand structure 33 comprises at least three tightening arms 330 arranged circumferentially at intervals, one end of each tightening arm 330 is hinged to the filter cover 2, a connecting rod 331 is hinged between each tightening arm 330 and the nut 32, and the other end of each tightening arm 330 is tightly matched with the inner wall of the drainage pipe structure 1. In this embodiment, the umbrella frame structure 33 includes four tightening arms 330 circumferentially spaced apart from each other, and the four tightening arms 330 are distributed in a cross shape with respect to the threaded rod 31, and when the threaded rod 31 rotates, because one end of the tightening arm 330 is hinged to the filter cover 2, the tightening arm 330 does not rotate with the threaded rod 31, but only radially expands under the driving of the connecting rod 331.

In addition, the umbrella frame structure 33 further includes an upper movable ring 332 and a lower movable ring 333 sleeved on the threaded rod 31, the upper movable ring 332 is fixedly connected with the filter cover 2, the nut 32 is fixedly connected with the lower movable ring 333, one end of at least three jacking arms 330 is hinged to the outside of the upper movable ring 332, and the connecting rod 331 is hinged to the outside of the lower movable ring 333. The upper movable ring 332 and the lower movable ring 333 are sleeved outside the threaded rod 31, the upper movable ring 332 and the lower movable ring 333 are in clearance fit with the threaded rod 31 respectively, the upper movable ring 332 is fixed on the filter cover 2, and the lower movable ring 333 can only move up and down on the nut 32 to generate corresponding actions, so that the connecting rod 331 is driven upwards to prop open the jacking arm 330.

Specifically, the connecting rod 331 is hinged to the middle of the jacking arm 330, and the connecting rod 331 can exert an effective opening action force on the jacking arm 330, so that the jacking effect of the umbrella frame structure 33 in the drainage pipe structure 1 is improved. In order to improve the installation accuracy of the filter cover 2 on the drain pipe structure 1, a positioning ring rim 20 is arranged on the bottom surface of the filter cover 2, and the positioning ring rim 20 is in clearance fit with the upper opening rim of the drain pipe structure 1. The positioning ring edge 20 is in clearance fit with the upper opening edge of the drain pipe structure 1, so that the purpose of positioning and installing the filter cover 2 is achieved.

The stopper structure is an annular flange 10, and the inner wall of the annular flange 10 is a tapered wall surface flaring downward. By utilizing the higher matching degree of the shape between the conical wall surface of the annular flange 10 and the tightening arm 330 of the umbrella stand structure 33 after being unfolded, the aim of stopping the umbrella stand structure 33 from being separated outwards is realized, and the aim of centering the umbrella stand structure 33 and the filter cover 2 after the umbrella stand structure 33 is unfolded can be also realized. In addition, the lower end of the threaded rod 31 is provided with a through hole extending in the radial direction, an anti-falling bolt 311 is inserted into the through hole, and the anti-falling bolt 311 is in blocking fit with the nut 32. The anti-dropping bolt 311 can effectively prevent the nut 32 from being screwed out and dropping from the lower end of the threaded rod 31 due to the fact that the threaded rod 31 is excessively screwed, and the structural reliability of the whole floor drain assembly is better.

In the embodiment 2 of the umbrella frame type floor drain assembly of the present invention, in order to meet different use requirements, the connection position of the connecting rod can be adaptively adjusted, as shown in fig. 4, the connecting rod 331 is hinged to the other end position of the propping arm 330, and can also exert an effective propping action force on the propping arm 330.

In other specific embodiments of the umbrella stand type floor drain assembly, in order to meet different use requirements, the umbrella stand structure is not limited to the structure in embodiment 1, the umbrella stand structure further comprises at least three tightening arms arranged at intervals in the circumferential direction, one ends of the tightening arms are hinged to nuts, connecting rods are hinged to the tightening arms and the filter covers, the other ends of the tightening arms are tightly matched with the inner wall of the drain pipe structure in a tightening mode, namely the arrangement positions of the tightening arms and the connecting rods are changed up and down, and the umbrella stand structure and the drain pipe structure can be fastened and connected.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
